In the previous section, we learned how to disable overriding. I used the final keyword before the accessor of the method that would prevent overriding Using final when declaring a class prevents inheritance.
final class class name{}
So let's look at an example.
<?php final class GoogleCar { } class Car extends GoogleCar { public function hello() { return 'hello'; } } $ever = new Car; echo $ever->hello(); ?>
The code above does not allow you to inherit GoogleCar using final.
But Car class is inheriting.
So I get an error
Result of the code above
Result
Clearing final in the code above allows inheritance, so no error occurs.
<?php class GoogleCar { } class Car extends GoogleCar { public function hello() { return 'hello'; } } $ever = new Car; echo $ever->hello(); ?>
Result
